UPDATE: Self-portraits: Holmes sticks out tongue, has gun

CENTENNIAL, Colo. (AP) -- Using a cell phone, James Holmes took photos of himself the night police say he shot up a Colorado movie theater.

He stuck out his tongue, smiled and posed with a Glock.

Police showed the photos in court on Wednesday, along with pictures of the theater they say Holmes took a month before the attack.

One photo included an exit door like the one investigators say Holmes propped open the night of the attack, which left 12 dead and 70 injured.

The testimony came as a hearing to determine if Holmes will stand trial wound down. Defense attorneys announced they would not call any witnesses. They had been granted permission to call two witnesses to talk about Holmes' mental state.

ORIGINAL STORYCENTENNIAL, Colo. (AP) -- The prosecution's final witness is expected to continue his testimony today at a hearing to determine if the Colorado theater shooting suspect should stand trial.

Detectives testified yesterday that James Holmes spent more than two months planning his attack on a midnight screening of "The Dark Knight Returns." They also said he rigged an elaborate booby-trap system in his apartment to distract police from the carnage at the theater, though the traps were never sprung.

One detective testified that Holmes, after his arrest, played with the paper bags they placed on his hands to preserve gunpowder evidence, pretending they were puppets.

Lawyers for Holmes are expected to present an insanity defense as they have previously stated that their client is mentally ill.

Holmes is charged with killing 12 people and injuring 70 in the July 20 massacre.
